Welcome to the board! I don't remember much of Diana or the mystery woman watching her and Roman/John.

I think when Marlena was being held at Maison Blanche, Stefano revealed he had taught her how to place chess while he was holding her captive on the island. I still think there is more to her missing years with Stefano than simply giving birth to the Gemini twins and being in a coma.

Hi rebel starter , actually I have always thought they should explore the years of Marlena missing. She was gone for quite a bit, & only some of it was covered. So much storyline could come from it IMO! She could have another child, lost memory's etc... I actually think at some point they WILL give Marlena a long lost child. Wether it was from the missing years, a twin of Belles, or something crazier like the miscarriage she had with Roman not being dead.
